The Red-bellied piranha
The Red-bellied piranha (Pygocentrus nattereri) is a species of piranha. This species lives in the Amazon River Basin, coastal rivers of north-eastern Brazil, and the basin of the Paraguay, Paraná and Essequibo Rivers. The red-bellied piranha has the reputation for being one of the most ferocious freshwater fish in the world. They have a set of razor sharp teeth which are capable of stripping flesh from prey and dead animals. As their name suggests, they have a reddish tinge to the belly when fully grown, although juveniles are a silver colour with darker spots
.The red belly has a set of teeth which will take triangular-shaped bites out of prey. Large schools will sometimes converge on large animals like anacondas, caimans, birds, and terrestrial mammals, stripping their bodies clean in a matter of minutes.
